I was at Leeds in 2002, the last year it was at Temple Newsam. We were right near the entrance to one of the campsites from the arena so had loads of traffic past our tents and the toilets were at the top of the hill.
It was Sunday night it all just went mental. Someone set a fire about 30ft away and started chucking deodorant cans on which generated a few decent sized fireballs. Then some genius threw a camping gas canister on, while it was on there a bloke tried to light his fag on the fire. He was very lucky, it went boom in a big way not much later. Bogs were on fire not long after that. I went and slept in the car as police helicopter was right above us all night. Absolute bedlam.
2003 at Bramham Park was like a village fete in comparison.
